PWM控制逆变稳压源电路的非线性模型及仿真

Nonlinear Modeling and Simulation for PWM Controlled Inverting Power Supply

讨论了采用整流-逆变-整流主电路结构的典型PWM控制逆变稳压电源电路的非线性模型。该模型将控制器的饱和非线性环节置于一局部反馈环之中，并采用触发器描述PWM控制的开关特性。利用该模型对某实际系统进行了仿真计算，给出了仿真计算结果。

This paper discusses nonlinear modeling for a PW M controlled inverting power supply The model explores a local loop including a saturation to characterize the actual controller and a flip flop to PWM' s swiching property,and then simulation results are given
